Vampire Dragons are members of the undead. They sustain themselves by drinking the blood of others. It is said that they are only “alive” at night, and seem dead or asleep during the day, as they cannot endure sunlight for long periods of time. Vampire Dragons can only reproduce by changing the eggs of other dragons, puncturing the shell with their fangs and injecting venom that kills the baby inside.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Maiti Damu is a fierce vampire dragon and a skillful fighter. He is one of the protectors of the clan's food for the fact he doesn't eat it... He abstains from biting the eggs of the clan for he knows Azurle will surely attack him, but he has bitten at least one egg so far. For a vampire dragon he is quite kind. He tends to play with the hatchlings from time to time. He will never drink from his clan mates and because of this the others trust him, so long as he keeps away from the eggs. His "mate" is his only vampiric companion Aima Thanatos, like him, she abstains from biting eggs as she does not wish other to share her undead fate.
